Genie Backup Manager uses non-proprietary ZIP64 compatible compression to reduce backed up data size and save space, supporting up to 264 -1 files within a zip archive as well as files that have a size greater than 4GB, for a zip file size that can reach up to about 18 million terabytes (more precisely, 2^64-1 bytes).
The Genie Backup Manager compression engine offers fast performance and low memory usage. Speed improvements reach 25%-75% in certain contexts. It also provides 15 to 20% better compression than other formats on many popular file types, especially XML data.
Users can choose between 10 levels of compression starting from no-compression, which packs the entire backup neatly within a single file, but without the overhead to the backup speed added by compression.
Choosing to backup data without compression causes GBM to copy the data to a single folder on the storage device while preserving the original folder tree structure, this makes data more accessible and less susceptible to corruption.
